energy efficiency
 Bottom-up formulae for calculating energy
savings

TD indicators – basic info
 Reflect overall final energy consumption trends rather than savings
resulting from specific energy efficiency improvement measures
 Implicitly reflect all energy savings (not onyl additional)
 Capture savings from horizontal and soft measures otherwise hard
to evaluate
 2009 as a starting year

Savings from early actions to be taken into account by BU methods
and added to TD results (avoiding double counting)
 3 levels recommended by the EC:




P: subsector level
A: if data for P are missing
M: when P and A cannot be applied
Eurostat data suffice for M indicators!
 24 recommended indicators for 4 sectors: residential, services,
industry and transport

TD indicators – what do you already
have?
 Excel template developed by EIHP with:
 Input data for calculation of TD indicators and savings according the EC
Manual (for 2009 and 2010)
 Simple end-use model for household (energy consumption for heating,
cooking, appliances) and transport sector (number of cars)
Energy consumption of households for space heating in toe per floor area in m2 adjusted for climatic conditions (P1)

BU methods – data requirements and
possibilities
 Specific final energy consumption before – after
 direct measurement with corrections
 estimate with model
 Program specific final energy consumption
before-after
 baselines available
 National average final energy consumption
before-after
 baselines available
11.10.2012
Seite 8
Page
BU methods - baselines
 Baselines determined for three types of
measures:
 replacement, retrofit without replacement,
acquisition of new equipment/construction of
new building
 National methodologies contain baselines – use
them in the lack of specific data!
 Stock average
 Market inefficient
 Market efficient

BU methods – what is already
available to you?
 All country methods with baselines available
from M&V&E project
 Summarized in the Final report

BU methods – data sources
 Direct measurements before-after


Rarely available, except in case of ESCO projects
Normalization needed
 Bills from distribution companies and retailers before-after

Normalization needed
 Equipment sales data (e.g. appliances, CFLs)

Rarely available in CPs
 Engineering estimates (with and without inspections)





Probably the most important source!
Modeling
Building statistics
Energy certificates databases
Data from implementing bodies (funds, agencies, donors)

Request data from them!
 Surveys (housing, market)

BU methods – data collection
 What can you do?


Define your data needs according to measures and methods to be used
for their evaluation - > national BU methodologies provide you
guidelines about data needs!
Timely send out calls to stakeholders for delivery of data (use this for
other purposes as well, e.g. to find out about activities on the supply
side)






Define deadlines for data delivery


Other ministries
Local authorities
Agencies, funds
Energy companies
Donors
You will for sure need to ‘chase’ stakeholders!
No magic recommendation 


Up to you how to handle this issue
Start now!

BU method – examples from Croatia
 Public lighting – very easy example 
 Metered data before-after available from the users of the Fund
and from ESCOs
 No need to use formula with default values
 Tips:
 Require data from local authorities (usually there are separate
bills for public lighting)
 Think in advance – how can you improve your methodology and
data collection system (e.g. asking only for road lenght)?

BU method for heating system replacement
Practically no data, sometimes even for square meters of a house
SHD determined according to year of construction (default value from methodology)
η available for new systems (invoices from installers required), but not for existing
(default value from methodology)
SWD also included (taken from Odyssee, but in general calculated according to
assumed water consumption in households)
 Tips:


Require data from locals, agencies and especially donors (many donor activities in the
region)
Consider in 2nd NEEAP prescribing minimal requirements in programs (e.g. minimal
efficiency of new heating system)
